With the increasing amount of Internet of Things (IoT) data, there is an increasing need to manage those data efficiently and securely. In this paper, we propose a decentralized and privacy-preserving IoT data sharing and management system based on the Interplanetary File System (IPFS) and the IOTA Tangle. Our system enables data owners to securely upload and manage their data on IPFS. We maintain the privacy of the data through Fuzzy Identity-Based Encryption (FIBE). Our system also includes a tag-based search mechanism, which allows data users to easily find the data they need without knowing specific transaction IDs. Compared with existing solutions, our system offloads data owners from local storage and backup and provides a more efficient and effective data search mechanism.
